Starting today, we're beginning to give out invitations to Google Voice users. If you currently use Google Voice, over the next few weeks, you'll see an "Invite a friend" link appear on the left-hand side of your inbox.

We'll be rolling out these invitations gradually, so don't worry if you don't see your invitations immediately. We're initially giving out three invites to each account, but we're planning to provide more invitations in the future.
